If you haven't already, you should download Karel Suhajda's Hersrch (see here). Dave Greene wrote a tutorial/example of its use here. Also, if you're curious about some of the history of B-heptomino/Herschel tracks, you should read this article by Dave Buckingham.

Speaking of, you should update your unsolved problems list to not include period-31 oscillators. (also, the note at the bottom should say "problem 35", instead of "problem 40")
